+## FAQ
+
+#### Q: `sudo voidnsrun xbps-install` exits with "environment variable VOIDNSRUN_DIR not found" error
+
+A: Add this line to `/etc/sudoers`:
+```
+Defaults env_keep += "VOIDNSRUN_DIR"
+```
+
+#### Q: Why applications launched with voidnsrun do not see my fonts?
+
+A: If you installed fonts on your main system, applications that run in the mount
+namespace can't see them because of custom `/usr` directory. You need to install
+them again into the altroot directory.
